Researchers in Canada and U. S. have revealed synthetic proteins aping the muscle protein in the humans, titin. In human beings, titin protein is mimicked by biomaterial.

The former is a muscle protein in humans. Also called connectin, is largely responsible for passive elastic properties of muscle and contraction of striated muscle.

These proteins become tough and pliable like muscle tissue, when cross-linked into biomaterials. These polymers can be, thus linked to form a rubber-like solid substance.

It can be fine-tuned by adjusting the compositions of the proteins, in order to resemble some specific types of muscles.

Besides above advantages, there are some loopholes in using these materials for implants, as these aren't made for tissue repair or renaissance. Also, such artificial materials can usually be hit by immune system or can be unwanted by the host's body.

Hongbin Li, Scientist, University of British Columbia, Vancouver, said, "We are currently developing robust methodologies to tune the mechanical properties of this biomaterial as well as designing new generations to incorporate functional and bioactive moieties". But to check the compatibility with the human tissue, the scientists still need to make an effort.
